D.Steel Connection Design Codes and Connection Types

The following tables indicate the allowable member types per connection for supported steel design codes in RAM Connection.

Steel design codes in RAM Connection:

RAM Connection Section Type	STAAD.Pro Section Type	Notes
I	Wide Flange^a
T	Wide Flange (cut into tee; `T` type specification)	Tee sections
HSS_Rect	Tube	Rectangular hollow sections
HSS_Circ	Pipe	Circular hollow sections
C	Channel
I2C	Channel (double back-to-back; `D` type specification)^b
L	Angle	Single angles
T2L	Angle (back-to-back; `LD` or `SD` type specification)^b	Double angles

Wide flange sections that have been assigned a cover plate (top, bottom or both, with the options: TC, BC, or TB), as a composite beam with the CM option, or a double profile with the D option will be designed using the base profile only.
Channel sections and angle sections are only designed with the options defined above. Channels front-to-front (type specification FR) and double angle star arrangement (heel-to-heel; type specification SA) are not designed.

Refer to TR.20.1 Assigning Properties from Steel Tables for details on STAAD.Pro steel section options.
